Description
Technical Field
The invention relates to the technical field of ship design and manufacture, in particular to an icebreaking ship type with double folding angle broadsides.
Background
The icebreaker is a service ship for breaking ice layer on water surface, opening up navigation channel, ensuring ship to pass in and out of icebound port and anchor ground or guiding ship to sail in ice area. It is divided into rivers, lakes, estuaries or ocean icebreakers. The ship body is short and wide, the ratio of length to width is small, the bottom is upwarped from head to tail, the head column is sharp and inclined forward, the overall strength is high, and the head, the tail and a waterline area are reinforced by thick steel plates and dense frameworks. The propulsion system mainly adopts a double-shaft or more-than-double-shaft multi-propeller device and adopts a diesel engine as motive power for propulsion. The propeller and the rudder are protected and strengthened. When the ice is broken, the head squeezing ice layer continuously breaks ice or repeatedly bursts into the ice during running. With global warming, polar activities such as shipping activities in the arctic region, oil and gas development in the arctic region, scientific investigation in the arctic region, and the like are increasing. The arctic region is mainly in the arctic ocean, the antarctic continent is also surrounded by the south ocean, and the movement of the two poles cannot be supported by ships in the ice region. The ice breaker is a professional ice area ship, can carry out ice breaking navigation and rescue towing on other ice area reinforced ships such as an ice area transport ship, an ice area scientific investigation ship and the like, and is an important tool for people to go deep into the two poles of the earth.
The icebreaker is an important open-road navigation platform in an ice area, and is required to have excellent ice breaking capacity and excellent maneuverability in ice, and the ship shape design is a main factor influencing the performance of the icebreaker. The side form of the icebreaker has an important influence on the turning performance of the icebreaker on ice. Generally, with the increase of the ice breaking thickness, the broadside angle of the flat edge area of the ship needs to be gradually increased to ensure the rotation performance of the icebreaker, but when the ice breaking capacity of the ship is high, the larger inclination angle can cause the problem that the displacement of the icebreaker under the same main scale is too much reduced to be balanced with the weight and the carrying capacity of the empty ship, and if the main scale of the ship is increased to increase the displacement, the problems of resistance increase, empty ship weight increase and the like can be caused.
